which fmu ?

i have d15b vtec jdm i can not get the 4500cc injectors so i decided to buy a fmu which percen is perfect for me for ex. 8:1 or 12:1 ?

i used a vortech 12:1 fmu on my turbo b18b. it did the job but ran like crap. whenever it'd boost, id just run rich and the boost never eased in like stock turbo cars, it would just boost all at once. you should just find some bigger injectors,get a piggyback and get it tuned. itll run a lot smoother and more reliable.
